Obama’s escalation of a war that’s already caused thousands of deaths will only destabilise his own allies and bolster al-Qaida

More than a decade after George W. Bush launched it, the “war on terror” was supposed to be winding down. US military occupation of Iraq has ended and Nato is looking for a way out of Afghanistan, even as the carnage continues.

From Pakistan to Somalia, CIA-controlled pilotless aircraft rain down Hellfire missiles on an ever-expanding hit list of terrorist suspects – they have already killed hundreds, perhaps thousands, of civilians in the process.
